Dear Jason,
The two pendulums may get in phase if (as is overwhelmingly likely)
their frequencies differ by a small amount; however, they will then continue
to change their relative phases (unless coupled appropriately) until they are
out of phase again. The same is apparently not true about human females; there
*does* appear to be a coupling based on olfaction.
Yours,
